Gastric cancer, also known as stomach cancer, occurs when malignant cells develop in the lining of the stomach. This disease typically progresses slowly over several years and often begins in the mucus-producing cells of the stomach lining.

Causes and Risk Factors

Several factors contribute to the development of gastric cancer:

• Helicobacter pylori Infection: This common bacterial infection causes chronic inflammation and ulcers in the stomach lining, significantly increasing cancer risk.

• Diet: A diet high in smoked, salted, or pickled foods and low in fresh fruits and vegetables is associated with a higher risk.

• Smoking: Tobacco use increases the likelihood of developing gastric cancer.

• Age and Gender: Gastric cancer is more common in individuals over 50 years old and occurs more frequently in men.

• Family History: Genetic predisposition and hereditary syndromes can elevate risk.

• Certain Medical Conditions: Conditions such as pernicious anemia, chronic gastritis, and gastric polyps are linked with increased risk.

• Obesity: Excess body weight may slightly raise the chance of developing the disease.

Symptoms

In its early stages, gastric cancer often causes no symptoms. When symptoms do appear, they may include:

• Indigestion or heartburn

• Stomach discomfort or pain

• Nausea and vomiting

• Loss of appetite

• Unintentional weight loss

• Feeling full quickly after eating

• Blood in vomit or stool (which may appear black)

• Fatigue caused by anemia
